Definitions

  • the present patent application for industrial invention relates to an installation and method for extraction of oil from olive paste.
  • GB 917 638 discloses a system for oil and fat extraction from animal or vegetal products that provides for alternate crushing and heating of the product, which is then pressed to extract oil. Heating is obtained with a tubular heat exchanger provided with air space wherein steam flows. The product is fed into the heat exchanger by means of a worm conveyor. In order to favor the transfer of product inside the exchanger, water is added to the product to make it more fluid. It appears evident that the addition of water considerably degrades the quality of the oil and produces emulsion during the following operations (especially during crushing in the disintegrator), impairing the extraction output.
  • EP2248880 in the name of the same applicant, which discloses a conveyor device composed of a heat exchanger with air space with circulation of hot water and worm conveyor.
  • a pressure rotary pump is used to maintain the conveyor device under pressure, so that the conveyor device is filled with olive paste during the passage of the olive paste.
  • the above guarantees a contact between the olive paste and the entire heating wall of the exchanger, in order to optimize the heat exchange efficiency.
  • the heat exchange efficiency improves for the continuous scraping of the internal surface of the heat exchanger caused by the olive paste moved by the worm conveyor.
  • ES 2 327 308 discloses a system that uses ultrasounds to achieve quicker and more uniform heating of a mass of olives during the extraction process of olive oil. Such a process uses the heating effect of ultrasounds on olive paste until it reaches a temperature of approximately 28-35°C. However, experimental tests have shown that the heating effect of ultrasounds does not achieve a significant temperature increase.
  • the purpose of the present invention is to eliminate the drawbacks of the prior art by disclosing an installation and method for extraction of olive oil that considerably reduces kneading time, while improving the quality of the oil without impairing the extraction output.
  • the installation for extraction of olive from olives comprises:
  • the piston pump of pulsating type, creates a pressure wave (a sequence of implosions and explosions of cellular membranes that favors the liberation of oil) that propagates in time and space to all the paste contained inside the worm conveyor. It can be defined as "milking" of olive paste, an alternate pressing of sinusoidal type as transmitted by a piston pump.
  • the linear motion of the piston is sinusoidal, in terms of space, speed and acceleration.
  • the installation of the invention may be optionally provided with a kneading station. It must be considered that preparation processes of the paste to oil separation occur during kneading. Oil is contained in olives in small cellular bags (vacuoles) with wall consisting in a cellular membrane. Crushing is not effective in terms of oil separation, because it breaks olives, but only a very few cellular membranes.
  • the delivery of the pump is higher than the delivery of the auger conveyor (pump and auger push the olive paste in series, one after the other). Therefore, a forced pushing action on the paste is generated in the air space between the revolving auger and the thermal exchange surface, thus keeping the surface of the conveyor clean, meaning that the product (olive paste) does not stagnate on the surface, favoring thermal exchange and avoiding local overheating of the olive paste.
  • the above improves the extraction output without impairing the quality of the oil.
  • ultrasounds can be applied in direct contact with the olive paste.
  • the synergetic effect of the ultrasound treatment that causes the breakage of the membranes and favors the coming out of oil, and of the conveyor allows for a considerable reduction of kneading time, thus guaranteeing high extraction output without impairing the quality of the oil.
  • the ultrasound treatment device can be installed upstream the conveyor.
  • the application of ultrasounds to the olive paste favors the breakage of the pulp cells, thus favoring the coming out of oil from the vacuoles.
  • the above makes the paste more oily and slicker, thus reducing friction on the internal walls of the conveyor. Therefore, the synergetic effect of the ultrasound treatment and the piston pump favors the passage of the olive paste in the conveyor, avoiding possible deposits of paste on the internal walls that may overheat and damage the quality of the extracted oil.
  • FIG. 1 the installation of the invention is disclosed, generally indicated with numeral (100).
  • Said installation (100) comprises:
  • An auger conveyor (4) is disposed between crushing station (1) and centrifugation station to transport the olive paste (P).
  • a piston pump (3) is connected to the conveyor (4) to feed the olive paste in the conveyor (4) in a pulsating way.
  • a first collection tank (7) is disposed upstream the piston pump.
  • a second collection tank (7') is disposed upstream the centrifugation station (6).
  • a volumetric pump (8) for example a single screw pump, is disposed between second collection tank (7') and centrifugation station (6) to feed olive paste to the centrifugation station (6).
  • the conveyor (4) can be optionally heated and, in such a case, it is defined as heater-conveyor (4).
  • a kneading station (5) can be optionally provided downstream the conveyor (4) to knead the paste (P).
  • the kneading station (5) is generally provided with a tank and a volumetric pump; therefore the second tank (7') and the volumetric pump (8) shown in Fig. 1 can be omitted.
  • the first tank (7) used to collect and transfer the paste, disposed upstream the piston pump (3) may comprise a bottom screw to feed the piston pump (3).
  • the first tank (7) may also be provided with kneading blades.
  • the installation (100) comprises at least one ultrasound generator device (2) to apply ultrasounds to the olive paste (P).
  • the ultrasound device or devices (2) may be disposed in any position of the installation, downstream the crushing station (1) and upstream the centrifugation station (6).
  • an ultrasound application device is disposed upstream the heater-conveyor (4).
  • the devices installed between crushing station and centrifugation station, in addition to the kneading station, are designed to reduce the thermal and oxidative stress of the olive paste, while exalting the quality of the extracted oil and improving the extraction output. It is known that, if too long, kneading tends to cause the development of aliphatic alcohols, in addition to other compounds, which degrade the quality of the oil.
  • the crushing station (1) is of traditional type and may comprise a hammer crusher.
  • the kneading station (5) is of traditional type and, as shown in Fig. 2 , comprises at least one basically cylindrical tank (50) with rotating blades (51, 51') supported by a shaft (52) disposed in axial position in the tank.
  • the blades (51, 51') have a different radial length.
  • the longest blade (51) brushes the semi-cylindrical internal profile concentric to the shaft of the kneading tank, whereas the shortest blade (51') does not.
  • the shortest blade (51') has helicoidal direction opposite to the longest blade (51') in order to give the fundamental relative motion between adjacent parts of the paste contained in the tank.
  • the peripheral speed of the blades has a higher limit that depends on the variety of olives, being the limit beyond which emulsion is developed.
  • the blades create a relative motion between adjacent parts of the paste (P) that remains inside the tank (50) to allow for mechanical scratching-breaking action of the cellular membranes.
  • the movement of the paste also favors the thermal exchange with the heating surface and the enzyme action at a temperature of approximately 27 - 35°C.
  • the speed of the blades must not be excessive not to impair the natural aggregation action of the oil (coalescence), which is crucial for the following centrifugation station.
  • the tank (50) generally has external diameter of about 60 cm and length of about 2-3 m.
  • the heater-conveyor (4) is adapted to convey the olive paste (P) and heat it uniformly to guarantee rapid kneading.
  • the heater-conveyor (4) comprises a cylindrical tubular structure (40) internally housing an auger (41) with bearing shaft (42), actuated by a suitable gear motor (43) to generate an auger conveyor.
  • the heater-conveyor (4) comprises an inlet (44) to load the olive paste (P) coming from the crushing station (1) and an outlet (45) to unload the olive paste (P) towards the kneading station (5).
  • the lateral walls of the cylindrical tubular structure (40) of the heater-conveyor are provided with air space (46) to allow for hot water circulation (A) by means of an inlet conduit (47) and an outlet conduit (48) provided at the ends of the air space (46).
  • the hot water circulation (A) guarantees a hot water temperature of about 35-40°C. In fact, a higher temperature would cause an excessive thermal shock of the olive paste (P).
  • the air space (46) is provided with helicoidal partitions (49).
  • the shaft (42) of the auger has an internally empty tubular structure and is crossed by hot water in order to heat also the central part of the flow of paste (P) moved by the heater-conveyor (4).
  • the internal diameter ( ⁇ ) of the tubular structure (40) of the heater is lower than half of the internal diameter of the kneading tank (50), preferably being one third of the diameter of the kneading tank.
  • the length (L) of the tubular structure (40) of the heater is higher than four meters, preferably six meters, to provide for suitable heating of the paste (P) inside the heater, with a temperature difference of about 10°C from the inlet to the outlet of the heater, in a very short transit time, such as 1-2 minutes. So, the paste (P) reaches the kneading station (5) at a temperature of about 20-30°C and kneading has a reduced length of 10-20 minutes, thus saving on time and energy.
  • the function of the kneading station is reduced because its effect is compensated by the effects of other devices installed between crushing station and centrifugation station. Certainly, with the same general effect, the useful volume of the kneading station is reduced.
  • the installation (100) provides for a piston pump (3) disposed upstream the heater-conveyor (4) to generate a pulsating effect on feeding of olive paste into the heater (4).
  • the piston pump (3) comprises a cylindrical chamber (30) where a piston (31) slides.
  • the piston (31) is connected to a connecting rod (33).
  • the connecting rod (33) is connected to a crank (34) that is driven into rotation by a drive shaft (35).
  • the pumping chamber (30) is connected to an inlet conduit (36) and an outlet conduit (37).
  • the outlet conduit (37) is directly connected to the inlet conduit (44) of the heater.
  • One-way valves (38, 39) are disposed in the inlet (36) and outlet (37) conduits of the piston pump to allow for correct direction of the flow of olive paste (P) towards the heater-conveyor.
  • the delivery of the piston pump (3) is higher than the delivery of the auger conveyor (41).
  • the pulsating action of the piston pump is of sinusoidal type because of its constructive configuration.
  • the ultrasound treatment device (2) comprises at least one ultrasound generator (20).
  • each ultrasound generator (20) comprises a transducer (21) to transform electricity into mechanical vibration at ultrasound frequency.
  • the transducer (21) comprises an enclosure that contains piezoelectrical crystals.
  • the transducer (21) is connected to an ultrasound emitter (22) that protrudes axially from the transducer.
  • the transducer (21) is provided with electrical contacts (23) connected to electrical wires (24) ( Fig. 4 ). As shown in Fig. 4 , the electrical wires (24) are connected to electricity generators (G).
  • the piezo-electric crystals of the transducer (21) when they are powered with electricity, they determine a high-frequency mechanical vibration that expands radially from the ultrasound emitter (22).
  • the ultrasound emitter (22) is inserted in a conduit (25) inserted in pipes (26, 27, 28) that transfer the olive paste from crushing station (1) to centrifugation station (6).
  • the olive paste passing through the conduits (26, 27, 28) comes in direct contact with the ultrasound emitter (22).
  • Low frequency ultrasounds are used, from 20 KHz to 100KHz, preferably at 20 KHz frequency.
  • the ultrasound treatment can be made for a variable time from 5 to 60 seconds. To that end, the transfer speed of the olive paste is suitably adjusted.
  • the power of the ultrasounds and the transit speed of the olive paste are chosen in order to prevent ultrasounds from heating the olive paste excessively, thus causing oil deterioration.
  • Such an ultrasound treatment causes heating of olive paste lower than 5 °C.
  • Processing in the experimental installation was carried out with two varieties of olives, with constant olive delivery to the installation, changing the temperature of processed paste (by means of the heater-conveyor (4)) and the kneading time in kneading station (5).
  • Each of the industrial lines used as reference is characterized by three kneading tanks in series (in overflow configuration) of 6,000 I/each, with single shaft and two-phase decanter (SPI 99 model), i.e. with only one subproduct.
  • the crusher and piston pump used in the lines of the industrial installation are identical to the experimental installation.
  • the parameters that were changed with experimental methodicalness (in the experimental installation) were kneading time and temperature (measured in the inlet of the decanter or horizontal centrifugation station).
  • a practically null kneading time was obtained by making the paste pass rapidly (without stopping) in the kneading tank (5).
  • the worm screw (4) was not heated for the temperature values with the best results. Therefore the effect can be entirely ascribed to the "milking" effect obtained by the piston pump (3) in the presence of the worm screw (4) that carries out a braking (contrast) action during passage of the paste pumped by the piston pump (3).
  • the worm screw acts as a pump with lower delivery than the piston pump.
  • the worm screw is a conveyor that guarantees the sealing (outwards) of the paste, because during its travel the paste is subject to a certain pressure basically due to the pumping effect of the piston pump.
